What is CodeSignal?

CodeSignal is a technical interview solution. According to the vendor, companies of all sizes already use CodeSignal’s Pre-Screen and Interview products to tap into underrepresented pools of candidates, increase speed-to-hire, and increase candidate pipeline yield. Studies have shown that companies who use pre-hire screenings see turnover rates reduce by 39%.

CodeSignal uses technology to predict a candidate’s interview performance. CodeSignal’s predictive assessments go beyond testing only for data structures and algorithms, instead they dive deep into subject-specific assessments. Assessments on CodeSignal’s platform support 38+ programming languages, provides an advanced real-world coding environment, coding scores, and utilize a proprietary AI-powered plagiarism check.

Overview of CodeSignal Features

CodeSignal offers tests in 38+ programming languages in a real life coding environment. Per the vendor, their platform is a “flight simulator for developers” that allows candidates to utilize familiar tools to edit, run and debug their code.

CodeSignal offers keystroke playback and an automated plagiarism checker. The ability to play back the candidate’s keystrokes means that their work can be evaluated by multiple members of the hiring team without the hassle of everyone attending the assessment live. Their AI plagiarism checker searches for suspicious results, such as similarities in candidate responses.

CodeSignal’s assessments can assist companies looking to diversify their teams. Companies can replace a resume screen, and the unconscious bias it may bring, with a coding assessment. Using assessment scores allow them companies to evaluate candidates purely on skill rather than any other factor.

Coding Tests

CodeSignal divides different coding tests up into unit test frameworks that assess a person’s technical skills. Examples of unit test frameworks include:

  • NUnit for .NET Framework

  • xUnit or NUnit for .NET Core

  • JUnit for Java

  • Mocha/Chai for JavaScript

  • PHPUnit for PHP

  • unittest for Python

  • RSpec for Ruby

  • UI tests using Galen

  • UI functionality tests using Puppeteer

Assessments can be set to run in a specific language, or can be language agnostic so that the candidate can complete the test in their preferred language.

Testing job-specific skills allow for companies to pre-screen based on candidate skills and helps to improve the interview to hire ratio, since only qualified candidates will be offered interviews.

Coding Interviews

Companies can use CodeSignal for more than just their screening assessments, as the platform also allows for coding interviews and whiteboard sessions. CodeSignal’s coding interview options are suitable for in-person or virtual interviews. Companies can choose interview tasks from a pre-existing library, or can easily import custom tasks from GitHub.

Using CodeSignal’s interview tool, companies can see how candidates interact with the tools they will use every day on the job and make more informed hiring decisions. Team members can interact with the candidate to evaluate their approach to solving problems.

CodeSignal will be used by very good and prolific tech companies like Dropbox, Roblox, etc. So if working in tech and trying to get a job at one of these great companies, CodeSignal is a must, so it's best you get used to it now. This will provide an advantage moving forward, as the more experience you have with CodeSignal, the easier it will be to demonstrate your technical competency in these companies' assessments.

Useful when one needs to provide a technical screening to a recruiter, or when one wants a quick practice in a particular area such as Dynamic Programming or backtracking. It is less useful in general practice cases, when one wants to engage or participate in discussions regarding the problem, when one wants to practice problems that are commonly given by a particular company, or when one wants a wide variety of problems that are innovative and unique.

CodeSignal can be useful to help determine the knowledge of engineers on more theoretical topics.
In my experience, CodeSignal can be very useful for more junior roles, and in particular when you receive a lot of applications and you need to have more data points on candidates before deciding whether or not to move forward with more interviews

It provides a very good candidate experience for live coding interviews.

It provides an effective, low overhead screening solution for inbound applications.

It provides a bank of interview questions.

It allows a company to define custom interview questions and share them with candidates.

It allows easily reusable links to be shared for coding exercises.

I think it's well suited for finding talent quickly since the questions asked are more akin to what one would be doing on the job and the automated evaluation. I really can't think of scenarios where this isn't appropriate at the moment.

If conducting interviews, CodeSignal is best in class and offers a full suite of modern, functional features to support developers and engineers of all experience levels. It allows quick editing and returns time to the interview by being dependable and efficient. I would use CodeSignal as the basis for all technical coding interviews as it allows reusability and standardizing across a big organization.

For most development roles, it is quite easy to set up a CodeSignal and it is often effective in filtering candidates in early stages. As a candidate; CodeSignal provides a well oiled user experience and acts as a method to set oneself apart from other candidates. In later stages CodeSignal has less efficacy in differentiating; it might be better to customize to your needs at this point.

CodeSignal is very well suited for the interview process. It streamlined the candidate experience and allows companies to manage their job applicants. I think it is less appropriate for use as a practice tool because there are alternatives that do it better. I think that CodeSignal is useful for students and employers.

If you are preparing for coding interviews and are looking to elevate your preparation with a real-interview like scenario, CodeSignal is a great platform that offers just that. You are able to simulate as if you were on a real coding interview with 2-4 coding questions. These questions are very similar if not identic to what you would get ask in a real scenario and many big tech companies use this platform to conduct their own assessments.

It is well suited to coding assessments for software jobs especially those for students since they can be hard to assess since students can have similar profiles as they go to the same school for the same program so this helps to differentiate them from one another and assess them.

Its really good if you want to practice working on your engineering skills. Also, if I happened to need to look for employees for a position, CodeSignal would provide a very easy way to filter out good/bad applicants. Its also very good to get a gague of how you are at coding relative to many others around the world.

I think code signal is one of the best platforms for organizations to better test the resource for their coding skills. Its way of conducting the test saves engineering time, reduces the risks that hiring companies have in technical interviews, and provides a cheating-free environment. The platform can be improved to make the new learners practice well on the platform and get used to it.

Codesignal is a great platform. It has a clean and relatively intuitive design. Users are able to interact/use it very easily. The issue is that during the coding tests, the problems can be very random. Sometimes, it's very hard other times it's very easy. I'm not sure how one would balance these issues, but it's an issue.

There is no way to carry out campaigns simultaneously with the collaboration of more people. The campaigns are automatically saved in the Mailchimp could while they are being created, in order to save information, however, this campaign cannot be edited by several people at the same time, as it would throw an error. I would like to be able to edit campaigns together with my colleagues, since that way we would obtain better results with the collaboration of more people.

In overall hiring process and finding problems for candidates for solving. CodeSignal is an interesting platform to have well defined problems statements to be solved wherein the explanation of the problem in case of failure to solve it is also provided. The scoring system is fantastic and the explanation is elaborative and clear.

As I mentioned in my previous answer, when you have a small team and a high time crunch, and you don't want to invest your resources in interviewing a larger pool of candidates, Codesignal helps you get a comprehensive judgment about candidates and filter out the best ones suited for the job thereby effectively reducing interview time for the team.

CodeSignal is very well suited when you want to get fast and accurate feedback about a candidate's technical skills. It allows you to concentrate on other aspects of the candidate, like social skills, and filter candidates that are not technically ready for the challenge. It's not so appropriate to evaluate logical reasoning.

Code signal is well suited for interview preparations and for companies as well to prepare questions from the site, but in my opinion, it is less suited for competition challenges. I think you should offer some coins or a cash reward for the highest positions in the competition to promote the product and attract more users.
